Jusimi Bicycle Alarm, Wireless Waterproof Anti-Theft Bike Alarm with Remote Control, 7 Level Sensitivity, 113dB Super Loud Sound, for Bicycle/Motorcycle/Window/Electric Tricycle/Door

Good buy for a shed perfect and easy to install

I bought this on a whim to try deter a disgustingly jealous person intentionally banging into our fence. Unsure if it would be sensitive enough and/or loud enough, let alone fit for purpose.Was I shocked! Amazing sensitivity, great build quality, discreet and small, excellent remote range and LOUD!! Boy oh boy is it LOUD! Perfect, just perfect.

UPDATEHAD THESE FOR A YUEAR NOW AND ONLY JUST REPLACED THE BATTERIES THEY WERE ONLY JUST DOWN TO THE YELLOW ON A BATTERY TESTER AND STILL WORKING.BROKE, THE PLASTIC CLIPS broke inside, returned and replacedRemember this is only a deterrent, in so far as it will hopefully shock someone.The unit is only fitted with zip ties, so it can be ripped off and thrown away, and of course ridden off and taken off later, USE A GOOD LOCK AS WELL.As a deterrent it is good, what it does do is let YOU know that your bike has either fallen over or is being touched, and loudly, if say you are in a cafe.IT WORKS and for the money there are NO complaints here in fact I have got one for the garden shed as well, great for out buildings.ALSO NOTE THEY ARE NOT ALL THE SAME CODE/REMOTE, I HAVE TWO NOW AND THEY ARE DIFFERENT, WHICH IS GREAT

Great & very good value for your money I have had so many off this. On different things just Bought this one for someone else e liked it just right for is electric bike very much good 👍

My last alarm died after several years so bought this oneWorks perfectly, very loud, very sensitiveGreat!

Not specifically meant for rucksack but worked well anyway! Left it inside rucksack when padlocked and set it with the remote. If you touched the rucksack even slightly, the alarm would activate, which was quite loud and very off putting to would be thieves

That was really, really helpful.I left the outside, somebody.Touch the and then alarm star really worthy works.Thank you so much

Item was not exposed to rain or anything and stopped working in 2 weeks, couldn't switch it off with remote and hat to take battery off with alarm going crazy. Terrible and waste of time and plastic.
